How this works

At break-even, every dollar of contribution margin funds a dollar of ad spend — so break-even ROAS is1 ÷ contribution margin. Keeping a target net margin means spending only the margin left over, which raises the ROAS you need. At a 35% margin you can spend up to 35% of revenue on ads before you lose money.

Balanced Corridor

Break-even ROAS in the 1.8x-3x band is workable. Protect margin and test into scale carefully — the gap between break-even and your target ROAS is where the profit lives.

At a 3.00x achieved ROAS you keep 1.7% net margin — about 1.08 profit per order. You are 0.14x above break-even, so this spend is profitable and there is room to bid up for volume.
